The Mainboard provides a series of jumpers to set the computer’s functions.This section explains how to change settings for your mainboard’s functionsthrough the use of the jumpers.
Clear CMOS Jumper: CLEAR_CMOS (J10)The onboard CMOS RAM stores system configuration data and has an onboardbattery power supply. The long-life battery has a lifetime of at least 5 years.If you want to clear the system configuration data from the CMOS RAM, usethe CLEAR_CMOS (Clear CMOS jumper). Follow the instructions below toclear the data:
You can clear the CMOS by shorting 1-2 pin whilethe system is off. Then return it to the 2-3 pinposition. Avoid clearing the CMOS while thesystem is on; this will damage the mainboard.WARNING!

Settings: Disa-bled and Enabled.
SDRAM Cycle LengthSet the time between SDRAM read command and when the data actually be-comes available.
Bank InterleaveSet the interleave mode of the SDRAM interface. Interleaving allows banks ofSDRAM to alternate their refresh and access cycles. One bank will undergo itsrefresh cycle while another is being accessed. This improves performance of theSDRAM by masking the refresh time of each bank.

When a password has been set, you will be prompted to enter it everytime you try to enter Setup. This prevents an unauthorized person fromchanging any part of your system configuration.
Additionally, when a password is enabled, you can also have BIOS torequest a password each time the system is booted. This would preventunauthorized use of your computer.
